Nowadays, the development of electronic technology is getting faster and faster. In order to allow us to use electronic digital products conveniently, capacitive touch-sensitive buttons are used in many digital products, but everyone is very curious about the principle of touch-sensitive buttons. What is it? Next, I will introduce the principle of touch-sensitive buttons to you. The working principle of the touch-sensitive button is that the touch-sensitive button has different working principles according to different types. From the working principle, it can be divided into two categories, resistive touch buttons and capacitive sensing buttons. The principle of capacitive touch buttons is that the human body senses capacitance to detect whether the mobile phone exists? If there is a finger, it will have a certain induction to the current, so that the smart phone can be operated. To put it simply, when the human body is close to the capacitive button, the current generated by the human body is coupled to the static capacitance, and the capacitance value of the pressed connection reaches the maximum, and the changed capacitance value at this time will transmit and transform the signal. , so that the capacitive signal is converted into some kind of control signal, so as to achieve the function of controlling the smart phone. The working principle of the resistance type is to use the human body to press the resistance, causing the resistance to change. The change of resistance will cause the whole circuit signal to change, so as to achieve the effect of controlling the smartphone. But his shortcomings are very big, the pressure must be to a certain extent, otherwise it will fail to achieve its purpose, which is also a major disadvantage of resistive touch buttons, so it will be eliminated by future digital products.

The manufacturing process of coil spring includes: rolling, processing of both ends (referring to compression springs) or the production of hooks (referring to tension springs or torsion springs), heat treatment and workmanship inspection, and important springs are also subjected to strong pressure treatment. There are two types of spring forming processes, cold rolling and hot rolling. When the diameter of the spring wire is less than or equal to 8mm, the cold rolling method is usually used. No matter the low cold coil or the hot coil spring, different heat treatments are required. After the spring is rolled and heat treated, surface inspection and process tests are required to identify the quality of the spring. After the spring is made, special treatment (such as strong pressure treatment or shot peening treatment) can be carried out to improve the bearing capacity and fatigue life of the coil spring.

Coil spring refers to a helical spring made of spring steel wire. There are many types of coil springs, which can be divided into ordinary cylindrical coil springs and variable diameter coil springs according to their appearance; they can be divided into left-handed springs and right-handed springs according to the direction of the helix. The cylindrical coil spring has a simple structure, is convenient to manufacture, and has a wide range of applications. When the load is large and the radial size is limited, two compression springs with different diameters can be used to form a combined spring. Variable diameter coil springs include conical coil springs, spiral coil springs and concave coil springs. Conical coil springs have better cushioning performance and can withstand larger loads. Spiral coil springs can store more energy and bear larger loads, but the manufacturing process is more complicated. The performance of the concave coil spring is similar to that of the conical coil spring, and it is mostly used for cushions and mattresses. The loading surface of the spring wire is round and rectangular, etc., and the circular section is more commonly used.

When it comes to food grade compression spring, although it is difficult to see it in our daily life, springs of different specifications play an important role in the construction of various building materials, and sometimes even a small spring can support huge object. The linear spring of food grade compression spring is suitable for various electrical appliances, motors etc. as it is the type of spring required, food grade compression spring is compressed by the load acting on them or their end parts, food grade compression spring is designed to pass Design the compression line to return to its original state so that the load is pushed back. food grade compression spring is mainly used in medical breathing equipment, medical mobile equipment, hand tools, home care equipment, shock absorbers, engine valves, etc. We provide food grade compression spring products, if you are interested in this, please contact us to know more More relevant information.

Food grade compression spring is a helical spring that is under pressure. Food grade compression springs are generally wire coiled at equal pitches and have a fixed wire diameter. Springs are generally of equal pitch. The shapes of food grade compression springs are: cylindrical, conical, convex and concave, and a small amount of non-circular shapes. There is a certain amount of space between the rings of food grade compression springs. Gap, when subjected to external load, the spring shrinks and deforms, storing deformation energy. food grade compression spring provides resistance to external load pressure. Food grade compression springs are generally wire coiled at equal pitches and have a fixed wire diameter. The food grade compression spring utilizes multiple open coils to provide resistance to external load pressure. That is, they push back against external pressure.

The main function ①Control the movement of machinery, such as electric springs in machinery, control springs in clutches, etc. ② Absorb vibration and elasticity, such as buffer springs under the impact of cars and trains, vibration-absorbing springs in couplings, etc. ③Maintain and output energy as power, such as clock springs, springs in machinery, etc. ④ Detecting force components, spring measuring force, spring spring, etc. The ratio of the spring's pitch to the deformation is like a slingshot, jumping, jumping, and rebounding. The harder. According to the force characteristics, springs can be divided into ordinary elastic springs such as disc springs, ring springs, leaf springs, spring springs, truncated conical scroll springs and torsion bar springs according to their shapes. Because it is simple to manufacture, and can be made into various types according to the situation, and the structure is simple, the most spring is used. For heat treatment, carbon spring steel, alloy spring steel, stainless spring steel, copper alloy, nickel alloy and rubber are commonly used. There are cold-rolling methods and hot-rolling methods for manufacturing springs. The diameter of the spring wire is less than 8 mm. Generally, the cold rolling method is used, and the hot rolling method is used for larger than 8 mm. Spring is a kind of elastic element widely used in machinery and electronics industry. Spring can produce elastic deformation when loaded, transforming mechanical work or kinetic energy into deformation energy, and then elastically deform and merge into original shape after unloading, transforming deformation energy into mechanical Work or kinetic energy. Spring class According to the force characteristics, the spring can be retractable spring, compression spring, elastic spring and bending spring; according to the shape, it can be divided into ordinary elastic springs such as disc springs, ring springs, leaf springs, spring springs, truncated cone springs and torsion bar springs. Because it is simple to manufacture, and can be made into various types according to the situation, and the structure is simple, the most spring is used. For heat treatment, carbon spring steel, allo
